Migraine

Migraine is a neurological problem that is characterized by chronic headaches, often accompanied by nausea and sensory changes. Most experts believe that migraine headaches are triggered by many a different set of environmental events including food and drink, weather and other factors. The research suggests that migraine triggers vary from person to person. Generally migraines are very painful on one side and can last from 4-72 hours. The most common symptoms of migraine include increased sensitivity to light and sound, nausea and vomiting. More than half of migraine patients will receive an unusual-visual, aromatic or any other type of sensory experience that generally arises before the headache begins.

According to the literature, there are four major categories of migraine studies after different processes to identify migraine trigger . They are also mentioned:

Challenge studies-there, who suffers from migraine are deliberately exposed to factors that may act as potential triggers to see if the pain occurs or not. Researchers using this approach have found very experimental evidence for very strong relationship between cause and effect triggers and headache.

However, several experiments using the approach challenge failed to confirm the results on the triggers, most of these studies do not focus specifically on individuals reporting a particular sensitivity to relaxation under investigation.

Treatment-based studies of this branch of study, migraine patients are advised to avoid contact with a particular set of migraine triggers (food items suspected in particular) for a period of time, to see if this reduces the rate / frequency of headaches. This will gradually identify the triggers, which, if it leads to avoid any headaches.

"Studies of treatment are generally considered as a mixture that some studies report beneficial effects of the control system that eliminates a large number of foods, while other studies say there are no benefits. In general, it is difficult to get many people to comply faithfully with regiments of foods in which many of their favorite foods are "off limits". For this reason, the study approach of treatment has not given either an effective treatment in general or the results of solid research.

In studies journal, patients are asked to keep a register of headaches and what were the factors they are exposed to that are on a list of suspicious fires. Some studies have used statistical analysis to determine if there was a strong causal relationship between exposure and onset of headaches later.

Survey studies in the survey studies, patients are invited to give their opinion on what they think and have observed their cause headaches.

In 1995, Silberstein and his colleagues conducted a survey of 500 migraine sufferers and found the following percentages believe their headaches were caused by different types of triggers such as:

Stress

79.0%

Temperature changes

44.0%

Before menstruation

37.2%

Changes in light

33.8%

Consumption of certain foods

30.0%

During menstruation

26.8%

Fatigue / insomnia / other

6.6%

Other events (combined)

13.2%
